Battery almost died while at stop light, now I'm hearing a dull buzzing sound
My battery has been dying for a little while but when I was at the stop light the other day my battery light came on and the radio turned off but the 4runner didn't shut down.
I turned off the lights, radio, and AC and went straight to the store and bought a new battery.
Only now I have a dull humming/buzzing sound coming from the engine bay.
I can hear it when it's in park and it slightly gets louder when I accelerate/reverse and can hear it adjust in volume when the AC compressor kicks on.
Is it the alternator that needs replacing now?
